RADIATOR FOR AUTOMOBILES.

Specification of Letters Patent. P t-in ated Sept. 21, 1909.

Serial No. 390,769.

To all whom it may concern:

Be it known that I, FRANK Tom), a citizen of the l nited States,residing at ()hicago in. the countyof Cook and State of Illinois, haveinvented certain new and useful improvements in Radiators forAutomobiles, of which the following is a specification.

In practice dittie'ulty has heretofore been experieucet'l in repairingbreakages and leaks, especially in an. interior and not easilyaccessible part of the radiator. Those falniliar with the art are awarethat insome insta'nces the matter of repairing a slight leak in aninzwcessible part involves not only a considerable expense but also adistigurw tion of the radiator which makes it undesirable for furtheruse.

'lhe object of the present invention is to provide a radiator thatinvolves the con.- .-.truction unit system; or in other words a systemenabling the radiator to be constructcd or reconstructed ofstrueturalunits having uniform characteristics.

An nn 'mrt'ant and peculiar feature of the t ment or unit which mayhappen to become disabled. I So far as I am aware this has never beendone in actual practice; and the. desirability of it is self-evident.

The present invention involves among other things a construction of sucha' nature that should one of the elemental units of the radiator becomedisabled upon the road or in a. loealitywhere repairs of the natureretpiired are impracticable a dummy can be substituted without impairingthe operativeuess of the radiator and without any dismlvantage theretowith the exception of the diminution of its capacity to the extent ofthe ren'ioved active elemental unit.

'lhese being the objects, the invention consists in the features ofnovelty that are hereinafter described with reference to theaccon'ipanying drawings, which are made a part of this spcciticatioi'i,and 111 which Figure 1 1s a front elevation of a radiator embodying theinvention in its presleeve omitted. Fig. 5 is a perspective View of thetop or cover of the header. Fig. (3 is a transverse section of a header.Fig. 7 is a perspective view of a bracing sleeve. Fig. 8 is afragmentary vertical section of a radiator embodying the invention andshowing the use of dummy headers. Fig. 9 is a perspective view of themiddle portion of a dummy header. r

A represents the ei'tston'iary casing or-out-e5 side jacket of theradiator of an automobile. in the present. instance it has an upper orinlet chamber a into which the water is admitted from the jacket of themotor and an outlet chamber 1) from which the water, having been coiledescapes, returning to the jacket of the motor. The characteristic of thepresent invention resides'in the manner of assembling the parts going tomake up the radiator. From the chamber a the .water passes in the firstinstance through a passage G into the so-called headers D of theradiator, whence the circulation takes place in the customarymanner. Thepassage C opens into one of the headers D and these headers are allcoupled up in such manner that when the water enters one it passesfreely from that one into the other, and soon in' series. These headershave interposed be--. tween them eiastie packinf s E, which are for bjthe sole purpose of i'naking water tight joints between them and aretied together by bolts i whieh aredistiiosed longitudinally with respectto the direction of the operation of the machine. The passage C is soconstructed that it enters into the bolt construct'ion forming a part ofthe connection between the several headers. In other words the passageC- is formed in a casting, a part of which receives the tie-bolts F.These tie-bolts are surrounded by elongated sleeves G which areperforated in order to permit the flow of water through them butotherwise perform the sole function of bracing the sides of the headersD in opposition to the resistance of the tie-bolts by which they aretied together.

As already intimated the purpose of this invention is to provide aseparable and segregable structure, so that in the event of thedestruction or disabling of any element ofthe radiator, the disabledelement may be removed and I have therefore provided dummy elements Hwhich may be Sl1bStl-',-'

tuted for the headers G. The efiect of this is that should the frontsection, become disabled and the operator being without asirnilai:section to replace it, he may replace it by the durnniy sections-"Hwhich restores the radiator to the operative condition, but simplyreduces its capacity to the extent of the removed section.

Another decided and very material advantage oi? the construction shownis that when a damaged section of the radiator requires to-be removed itcan be done with facility, the radiator in its entirety being made up ofa number of absolutely similar units, anyone which can be removed or l5replaced with. facility. From the headers I) the" water passes downwardtl'irough the radiating tubes 1 and into the lower headers D and thenceto the outlet J. The lower headers are con- QOstructed and arrangedprecisely like the up or headers, and have similar accessories,

which bear the same reference letters as the accessories of the .upperheaders, plus the f. prime mark Whatl claim as new is: i 1. In aradiator thecombination of a plurality of circulating tubes, eachhaving.

at each of its ends, respectively, a headersection, means for formingtight oints between the header sectlons, upper and lower water chambers,tubes passingthrough the upper and lower header-sections, and a duits,header-sections communicating with into close contact with each other,perforated tubes disposed horizontally and passing through saidheader-sections, and in-let and out-let passages communicating with saidhorizontal conduits, "respectively.

4. In a radiator the combination of a plurality of vertical circulatingtubes or condui'ts, header-sections with which the upper andlcwer-endsof said conduits communicote, respectively, an upper, or inlet ohamher, a water jacket, iii-passage leading from the Water jacket,a perforated tube arranged within the headers at the. upperends of theconduits, a tie bolt adapted to draw the header-sections togetheigand'dummy headere sections adapted to be inserted, in the place of disabledactiveheader sections.
